[QUOTE="Greyfox, post: 1604731, member: 10291"] Time will tell if there is a material difference in barrel life between the two rounds. IMO, of all the aspects of rifle shooting, there is more “smoke” floating around about barrel life then all aspects combined......90% of it, parroted.....and claims rarely if ever substantiated. It’s hard to understand the neurosis about barrel life. I do understand the neurosis about precision and consistency. For PRS competition(usually 10 round stages over 1.5-2 minutes between cooling) shoot a 6.5x47. Under these conditions I see about 2200 rounds of barrel life before a .5MOA/flyer degradation. This is consistent with both the 6.5CM and 6.5x47’s with the other shooters in our club. If anyone believes the larger 55-65gr powder capacity 6.5’s will come close to this barrel life under the same conditions, I have a property in Florida....... For hunting, I have been hooked on my 6.5x284’s for over a decade simply because they deliver superb bench-rest grade precision and consistency at 1000 yards .... in a hunting class rifle. My primary 6.5x284 hunter is going on ten years old, seen over 1000 rounds, and has zero throat erosion or fire cracking. I seldom run it more then warm to the touch. It’s very effectively accounted for dozens of game animals from 200 to 1188 yards, and moderate varmints and rock/steel busting even further. It has been exceptionally consistent and has rarely required a zero adjustment. My other two hunters in the 6.5x284 deliver comparable performance. Of course other cartridges may be as capable or better then this, but I just haven’t owned one of them....and LOL, I’m perhaps too old to start searching now. I think barrel the barrel on the rifle mentioned may get another 500 rounds before it gives up the ghost. But if it died tomorrow I’d give it a proper burial, and happily replace it. [/QUOTE]
